samsung 50pq3000 cutting out.

[charlierfc]

hi all, how are you all today?

ok i got my hands on this plasma tv, when its turned on at first it comes on ok for about 30 seconds then turns off, comes back on after a min then repeats the process.

i opened up tv, no bad caps or any dry solders. the vs is bang on though the va is a couple volts low, tried to ajust but best i can get is just 1 volt below.

i have disconnected the sus boards but the tv still seems to turn off as when they are connected

the psu board is a eay58316301. cant find any repair kits to give me a hint that its that.

any body dealt with these plasmas before?

i know of a common fault with another 50 samsung plasma where 3 resistors go bad along with a diode and a volt reg. but i removed the 10 ohm resistors and they test ok. i when over the transformer joints to check for dry solders.

any hints?

thanks in advance, charlie

Posting pictures of the back of your tv showing the boards with clear pictures may help you more with fixing your problem

have u tested any more voltages on the PSU ?

This is an Lg set, firstly check the pson signal that tell the psu to turn on and see if that voltage disappears, also could you take pictures of the boards please ?
